hoknamahn Posted November 28, 2005 Share Posted November 28, 2005 Hey guys! I wonder how to break the wall (say polygonal grid or stamped on that grid geometry) by particles? Quote Link to comment Share on other sites More sharing options...
aracid Posted November 28, 2005 Share Posted November 28, 2005 hey hoknamahn is there any reason why u wouldnt wanna try dops? Quote Link to comment Share on other sites More sharing options...
hoknamahn Posted November 28, 2005 Author Share Posted November 28, 2005 hey hoknamahnis there any reason why u wouldnt wanna try dops? 22899[/snapback] I'm asking abt DOPs Quote Link to comment Share on other sites More sharing options...
aracid Posted November 28, 2005 Share Posted November 28, 2005 I'm asking abt DOPs 22901[/snapback] mmm, i didnt notice the subsection... i wonder if the copy object DOP is what u looking for hdox://houdini/content/helpcards/dop/copyobject.xml i think that might help aracid Quote Link to comment Share on other sites More sharing options...
Andrei_S Posted November 28, 2005 Share Posted November 28, 2005 But how can i made particle as RBD Object may be sphere or box? Quote Link to comment Share on other sites More sharing options...
hoknamahn Posted November 28, 2005 Author Share Posted November 28, 2005 I'm looking for a ways to move a pieces of geometry (fractured object) by particles. Quote Link to comment Share on other sites More sharing options...
michael Posted November 28, 2005 Share Posted November 28, 2005 well the good old Breaking Ica tutorial might help: http://odforce.net/forum/index.php?showtopic=3362 maybe a description of what you want to do would help... Quote Link to comment Share on other sites More sharing options...

edward Posted November 28, 2005 Share Posted November 28, 2005 Try looking at the example file in the help for the POP Solver DOP. Quote Link to comment Share on other sites More sharing options...
hoknamahn Posted November 29, 2005 Author Share Posted November 29, 2005 Try looking at the example file in the help for the POP Solver DOP. 22909[/snapback] Huh... I have a RBD Fractured Object (polygonal grid with unique points) and POP Object. But simulation looks as it's not Fractured Object but usual RBD Object. When the particles hit that object the object doesn't scatter on a parts and turns entirely. Quote Link to comment Share on other sites More sharing options...
edward Posted November 29, 2005 Share Posted November 29, 2005 Try also looking at the RBD Glue DOP examples. Quote Link to comment Share on other sites More sharing options...
hoknamahn Posted November 29, 2005 Author Share Posted November 29, 2005 Maybe someone can made a simple example? Quote Link to comment Share on other sites More sharing options...

hoknamahn Posted November 29, 2005 Author Share Posted November 29, 2005 Thanks a lot guys But what if I wanna brake a grid? (not copied geometry) Quote Link to comment Share on other sites More sharing options...
hoknamahn Posted November 29, 2005 Author Share Posted November 29, 2005 Never mind. I understand my mistake. Quote Link to comment Share on other sites More sharing options...
Andrei_S Posted November 29, 2005 Share Posted November 29, 2005 but i don't understand how can i made particles as volume object, may be sphere or box? Quote Link to comment Share on other sites More sharing options...
hoknamahn Posted November 30, 2005 Author Share Posted November 30, 2005 but i don't understand how can i made particles as volume object, may be sphere or box? 22936[/snapback] Copy Objects DOP? Interesting question. I have another one question: when I change geometry from boxes to grid (in the brake_wall_by_particles.hipnc scene) particles doesn't see the grid. All my experiments with breaking of the grid (or other 2d object) by _particles_ are failed So I still wanna see example with breaking of the _grid_. Any suggestions?

hoknamahn Posted November 30, 2005 Author Share Posted November 30, 2005 And one more... How to group the polygons of the dop objects with the rule "all polygons that was pushed out by particles"? For example if I want to apply the gravity force to the polygons that was pushed out from the broken grid. Quote Link to comment Share on other sites More sharing options...
Andrei_S Posted November 30, 2005 Share Posted November 30, 2005 for group you can use this expression dopoption(".", $OBJID, "Position", "tz") < -0.5 for example. and look DOP example file !!!!! Quote Link to comment Share on other sites More sharing options...
